Question of the Day

Adding and Dropping Columns I

I have this table in my SQL Server 2022 database: 

CREATE TABLE [dbo].[CityList]
(
[CityNameID] [int] NOT NULL IDENTITY(1, 1),
[CityName] [varchar] (30) COLLATE SQL_Latin1_General_CP1_CI_AS NULL
) ON [PRIMARY]
GO
I decide to add two new columns for the StateProvince and Country. What code should I use?
